Summary: This study investigated the potential of the polar diatom Fragilariopsis cylindrus in producing fucoxanthin (Fx) and the inter-convertible couple diadinoxanthin-diatoxanthin (Ddx+Dtx) by manipulating the growth light climate and temperature. The results showed that F. cylindrus is well-suited for Fx and Ddx+Dtx production under conditions of low temperature and light intensity, reaching similar productivity levels as temperate counterparts.

Summary: The study revealed that the pillar coral population in Florida has been reproductively extinct for decades, with severe losses. Long-term chronic stressors have been affecting the population's recovery, while back-to-back years of coral bleaching and thermally-exacerbated diseases led to a sharp decline in population numbers.

Summary: Most stony corals release their gametes into the water column through broadcast spawning, where successful fertilization depends on the activation of sperm motility. In this study using the broadcast spawning coral Astrangia poculata, it was found that cytosolic alkalinization of sperm activates the pH-sensing enzyme soluble adenylyl cyclase (sAC), which is essential for sperm motility. Results also revealed that sAC activity leads to protein kinase A (PKA) activation and contributes to sperm motility activation. This study suggests that the pH-dependent sAC-cAMP-PKA signaling pathway is conserved in different coral sexual systems.

Summary: The polar night at high latitudes poses a challenge to photosynthetic organisms. This study used flow cytometry to investigate the acclimation of a population of diatoms to darkness and found distinct subpopulations with specific traits. The survival of these diatoms in darkness relied on reduction of metabolic activity and consumption of carbon reserves.

Summary: Diatoms are important primary producers in cold, turbulent, and nutrient-rich surface oceans, particularly in polar regions. The cold-adapted pennate diatom Fragilariopsis cylindrus is considered a key species in polar oceans and sea ice due to its ability to thrive in different environmental conditions if temperatures are low. This perspective paper provides insights into recent molecular research on F. cylindrus and discusses its role as a model alga for understanding cold-adapted life.

Summary: The discovery of multi-species synchronous spawning on the Great Barrier Reef in the 1980s led to efforts to document spawning times globally. The Coral Spawning Database (CSD) compiles data from over 100 sites in the Indo-Pacific region to provide open access for studying coral reproductive biology. The CSD aims to accelerate understanding of coral reproduction and to establish a baseline for evaluating future changes in reproductive patterns.

Summary: The study examined the biological function of rGnRH in inducing ovulation and spawning in Sterlet sturgeon broodstock. The highest dose of rGnRH was more effective in inducing spawning, suggesting its potential for artificial reproduction of sturgeons and treatment of reproductive disorders in fish.

Summary: Rainbow trout lines with different spawning seasons were crossed to study the impact on spawning date and gamete characteristics of offspring. The hybrid progeny showed a later spawning date and exhibited a classic phenotypic distribution pattern of heterozygous F1 hybrids. The study provides valuable information for hatchery production of year-round seedstock and genetic analysis of spawning date in rainbow trout.

Summary: The study suggests that spawning zones may be a universal trait of Atlantic cod and not limited to specific environments or migratory behaviors. Age at maturity derived from spawning zone data shows similar trends to gonad maturity stages, but there is a lag of one to two years between spawning events and sexual maturity, likely reflecting a stabilization of energy partitioning.

Summary: The iconic pillar coral, severely impacted by stony coral tissue loss disease (SCTLD) in the Florida Reef Tract, saw a precipitous decline in its population. A collaborative rescue project collected colony fragments for safekeeping at facilities, providing opportunities for refining husbandry practices, developing treatment options for SCTLD, maximizing growth and providing a source of genetic diversity for restoration. The rescued ex situ colonies represent the entirety of the restoration potential for pillar coral in Florida, with the wild population continuing to decline.

Summary: Tetrodotoxin (TTX), an extremely potent neurotoxin, is believed to be a biological defense compound. Recent research has shown that pufferfish are attracted to both TTX and a related compound 5,6,11-trideoxyTTX. This study examined the location of TTXs in various tissues of spawning pufferfish and found that TTX levels were higher in the Kamogawa population compared to the Enoshima population. There were no significant differences in TTX levels between sexes, but the distribution of TTXs in tissues differed significantly between males and females.

Summary: Novel methodologies now allow for tracking the complete geographical movements of seafood species, providing valuable information for consumers and resource managers. This mapping requires a synthesis of natural and social sciences, including knowledge of fish population abundance, egg output, larval dispersal, and fisheries assessment.

Summary: Government and private organizations invest heavily in artificial reefs to enhance fish populations for recreational fishermen. Providing a spatial refuge for benthic fauna on artificial reefs can result in elevated fish abundances and increased angler success. Experimental manipulation of epibenthic prey supports the role of productivity in controlling artificial reef fish assemblages.
